Holy cow! SurveyUSA just posted fully red-and-blue election preview maps based on 30,000 interviews in all 50 states! Almost fully clickable (they're working on it) so you can see the data behind the color!
Here they are! Can you tell which map is Clinton vs. McCain and which is Obama vs. McCain? I'll give you a hint: at this point both Democrats are winning the electoral match-up. Take a guess and then click to find out!
